Leeb Portable Hardness Testing Machine 0° ~ 360° Measuring Direction
Leeb hardness tester according to the Leeb hardness measurement principle can be easily and quickly
measure a variety of metal materials, and instantly display the value of measured hardness. And it can
swiftly convert the hardness value in different hardness scales.
ADVANTAGES:
1. Wide measuring range. Based on the principle of Leeb hardness testing theory. It can measure the Leeb
hardness of all metallic materials.
2. Large screen LCD, showing all functions and parameters.With EL background light.
3. Seven impact devices are available for special application. Automatically identify the type of impact
devices.
4. Test at any angle, even upside down.
5. Direct display of hardness scales HRB, HRC, HV, HB, HS, HL.
6. Large memory could store 100 groups (Relative to average times 32~1 ) information including single
measured value, mean value, impact direction, impact times, material and hardness scale etc.
7. Battery information showing the rest capacity of the battery and the charge status.
8. User calibration function.
9. Software to connect to PC via USB port.
10. Thermal printer integrated, convenient for in field printing.
11. NI-MH rechargeable battery as the power source. Charge circuit integrated inside the instrument.
Continuous working period of no less than 150 hours (EL off and no printing).
12. Auto power off to save energy.
13. Outline dimensions:212mm×80mm×32mm
